This guide, intended for participants in the sixth course of the National School Resource Network Core Curriculum, contains an activity/content summary for each module of the course, worksheets, and background materials. The purpose of this course is to increase awareness of comparatively low-cost approaches to crime prevention through environmental design. A full range of physical design strategies that can be implemented in schools is presented. Many of the strategies can be applied by school personnel and students. An assessment checklist can be used by school personnel to identify environmental problems. (Author/MLF)
